2. I use Windows 2000/XP/Vista/7 and WB in 3D mode but the game crashes when I switch planes.

Solution: If you are running Windows 2000/XP/Vista/7 and want to be able to play in 3D you will probably need to remove a tick from "Display properties>Effects>Use transition effects for menus and tooltips", otherwise WB may crash when you change the plane.

You can find properties at "Display properties->Appearance->Effects" or (as Administrator) also by right-clicking "My Computer" under "System Properties->Advanced->System Ressources->Visual Effects", where you can anyway choose the "Optimized for speed" option.
